help (uk crisis team qs)

does anyone here know like, when you should call the crisis team
im feeling very suicidal but i know i wont act on it but the pain is excruciating
i cant breathe
i feel so terrified of what might happen

My personal opinion is that regardless if you will act on it or not, it is still a problem for you (as you admit) and therefore you SHOULD seek out assistance. Call the crisis team, tell them exactly what you have just said here, and find out how they recommend you proceed. Getting help is important, always.

I have asked for help when very desperate from Police, docs, Samaritans and mental health, none of them cared or did anything.
Samaritans were hideous and lady told me to just kill myself!!!!!!!!!!!!!!!!!!!! next Samaritan suggested I go out and buy a new outfit to cheer up!!!!!!!!!!!!!!!!!!!!!!!!!
Police told me to go to doc or just cope and if i did kill myself they'd come and clean and pick up pieces afterwards!!!!!!!!!!!!!!!!!!!!
Docs dont know what to do, send you to mental health who screw you up EVENMORE!!!!!!!!!!!!!!!!!!!!!!!!!!!
